Jon is an Assistant Professor directing research in Software Engineering and Software Systems at George Mason University. His research makes it easier for developers to create reliable and secure software by improving software testing. Jon’s work on accelerating software testing has been recognized with an ACM SIGSOFT Distinguished Paper Award (ICSE ’14 – Unit Test Virtualization with VMVM), and was the basis for an industrial collaboration with Electric Cloud. His program analysis research has resulted in several widely adopted runtime systems for the JVM, including the Phosphor taint tracking system (OOPSLA ’14) and CROCHET checkpoint/rollback tool (ECOOP ’18). His research has been funded by the NSA and the NSF, and he is the recipient of the NSF CAREER award. At George Mason, Jon teaches courses in distributed systems, web development, and program analysis. His teaching at GMU has been recognized with a departmental award. Jon serves on a variety of program committees, and has been involved in the logistical organization of many recent OOPSLAs. As part of his efforts to broaden the participation of underrepresented groups in computing, Jon co-organizes the PL/SE mentoring workshop at SPLASH (in 2017, 2018 and 2019).
His other interests include photography and cycling.
Jon is currently recruiting exceptional students at all levels (undergrad, masters and PhD) to join his research group. If you are interested, please send him an email.
